This weekend I took a couple of boys to the beach (family members) and wanted to get some video of them trying to surf and using a boogie board, (in some very poor surf conditions). Something unexpected happened, through the low resolution of the goggles, I mistook some other kid and hovered up close. As he turned to face me, I realized he wasn't the kid I was expecting and instead of a surfboard, he had a surf casting reel. He cast his lure at my quadcopter. I didn't really notice what had happened until later when I reviewed the video from the GoPro. In the slow motion section, you can see the lure whiz past just below me.
Anyway, he missed and I was lucky. I finished out the flight and landed unaware.. and will be more careful in the future!
